Abstract

An ejection cooler for protecting optical equipment that installs an optical window that divides the inside of the cooler body into two areas so that the surface of the cooler body in which the light source generator for irradiating a light source to observe a specific part of a flow area where a flame exists is installed can be cooled by film cooling, and that forms the slit-shaped ejection port vertically so that the light passes through the optical window and is irradiated through the cooler body. Therefore, the amount of cooling air can increase and the ejection pressure can increase to protect the light source generator from high temperatures, and when the light source passes through the ejection port, the beam can be spread so that an optical path is formed in the form of a thin surface that gradually widens in the vertical direction.
